Image as cursor, should move when you scroll

I replaced my cursor with a bigger image in order to have a big cursor on a website. Actually, it works well and follows the mouse but as soon as I scroll my page, the cursor stays at the same position as before and update as soon as I move my mouse again.

My idea would be to let the mouse move as soon as you scroll, and not teleport later.

Here is the code so you can understand. thanks for the help!

  $(document).on('mousemove', function(e){
    $('#custom-cursor').css({
      left:  e.pageX -30,
      top:   e.pageY-25,
            pointerEvents: 'none'
    });
  });

#custom-cursor{
    width: 230px;
    height: 300px;
    position: absolute;
    background-size: 230px 300px;
    background-image: url("https://i.imgur.com/6uh0F5h.png");
}

<div id="custom-cursor"></div>

Solution

Well, you also need to calculate the relative mouse position by the amount of the scroll distance like below :

Edit: I only did it for vertical scrolling you may also need to do the same thing for horizontal scrolling.

let lastX, lastY, lastScrolled = 0;;
$(document).on('mousemove', function(e) {
  lastX = e.pageX - 30;
  lastY = e.pageY - 25;
  $('#custom-cursor').css({
    left: e.pageX - 30,
    top: e.pageY - 25,
    pointerEvents: 'none'
  });
});

$(window).scroll(function(event) {
  if (lastScrolled != $(window)
    .scrollTop()) {
    lastY -= lastScrolled;
    lastScrolled = $(window)
      .scrollTop();
    lastY += lastScrolled;
  }
  $('#custom-cursor').css({
    left: lastX,
    top: lastY,
    pointerEvents: 'none'
  });
});

#custom-cursor {
  width: 30px;
  height: 30px;
  position: absolute;
  background-size: 230px 300px;
  background-color: red;
}
